Abstract: The present invention discloses a novel construction arrangement in a packaging machine for incubator trays, which enables the general automation of the packaging process of eggs in incubator trays. The packaging machine for incubator trays accepts several arrangements and capacity for four, five, six and twelve eggs, depending on the incubator trays to be used. The packaging machine for incubator trays of the present invention exhibits great improvements. One of these great improvements is related to the introduction of an automatic feeder for trays, commonly called tray dispenser or denester for incubator trays. Another great improvement refers to a constructive change in one of the main elements of the disclosed machine, and this change was made in order to stop vibrations that the eggs were eventually exposed. The benefits obtained from the use of the packaging machine for incubator trays, the main object of this invention, are related to the possibility of greater automation of the process.

Abstract: The present invention discloses a novel improvement applied to egg grader machines used in poultry farms and the like. Said continuous egg grader machine differs from other egg grader machines because it does not comprise the above-mentioned 90-degree curve existing in the egg circuit, i.e., the continuous egg grader machine of the present invention comprises a completely continuous linear circuit, wherein the great advantage of using the continuous egg grader machine disclosed herein is related to the gain obtained by the egg reduced speed when multiple rows of eggs are provided.
